Colonoscopy cuts colorectal cancer deaths, study shows

A study found colonoscopies reduced the risk of death from colorectal cancer by 53% for patients who had precancerous polyps removed during the procedure. “Not all adenomas become cancers, and not all cancers cause death,” said lead author Ann Zauber, a Sloan-Kettering statistician. However in many cases, Zauber said, “we have gotten those that would have had the potential to go on and cause a cancer death.” The New York Times (tiered subscription model) (2/22), Reuters (2/23)
